Abstract
Description
Füllstandsanzeige für Level indicator for
Saugre inigungsgeräte Die Erfindung betrifft eine Füllstandsanzeige für Saugreinigungsgeräte gemäß dem Oberbegriff des ersten Anspruchs. Saugre inigungsgeräte The invention relates to a level indicator for vacuum cleaning devices according to the preamble of the first claim.
Bei einer Bauart eines Saugreinigungsgerätes (DE-Patentanmeldung P 30 21 520) ist bis auf die Durchführung für die Saugluft ein in sich abgeschlossener Schmutzwasser-Sammelbehälter vorgesehen, bei dem gegenüber der Ableitung der Saugluft ein Schwimmerventil angeordnet ist, das bei max. Wasserstand schließt.In one type of vacuum cleaning device (DE patent application P 30 21 520) is a self-contained one except for the implementation for the suction air Dirty water collecting tank provided in the opposite of the discharge of the suction air a float valve is arranged, which closes at maximum water level.
Dadurch baut sich im Kanal zum Sauggebläse ein max. Unterdruck auf, der in Verbindung mit einer ansteigenden Temperatur im Gerät zu Beschädigungen des Gebläsemotors von Gehäuseteilen oder auch des Schwimmerventils führen kann.As a result, a maximum negative pressure builds up in the duct to the suction fan, which, in connection with a rising temperature in the device, can damage the Fan motor can lead from housing parts or the float valve.
Der Erfindung liegt die Aufgabe zugrunde-ein Saugreinigungsgerät gemäß dem Oberbegriff des ersten Anspruchs zu schaffen, bei dem in Abhängigkeit vom Füllungsgrad des Schmutzwasser-Sammelbehälters schließlich das Gerät abgeschaltet wird. Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale der ersten Anspruchs.The invention is based on the object-a vacuum cleaning device according to to create the preamble of the first claim, depending on the degree of filling of the dirty water collecting tank, the device is finally switched off. The solution this object is achieved according to the invention by the characterizing features of first claim.
Durch die Anordnung der Druckmeßeinrichtung im Kanal zum Sauggebläse ist eine ständige Überwachung des Unterdrucks möglich, so daß bei geschlossenem Schwimmerventil das Gerät selbsttätig abgeschaltet wird, was gleichzeitig eine Aufforderung an den Betreiber darstellt, nunmehr den Schmutzwasser-Sammelbehälter zu entl@@ren.Due to the arrangement of the pressure measuring device in the duct to the suction fan constant monitoring of the negative pressure is possible, so that when the Float valve the device is switched off automatically, which is also a request to the operator to empty the waste water collection container now.
Die Erfindung wird anhand eines in der Zeichnung schematisch wiedergegebenen Ausführungsbeispiels erläutert.The invention is shown schematically on the basis of one in the drawing Embodiment explained.
In einem Gehäuse 1 eines Saugreinigungsgerätes befindet sich ein Schmutzwasseraufnahmeraum 2, in welchem ein Schmutzwasser-Sammelbehälter 3 angeordnet ist. Der Schmutzwasser-Sammelbehälter läßt sich durch einen darüber vorgesehenene abnehmbaren Deckel 4 nach oben herausheben. Durch den Deckel 4 und eine Abdeckung 5 des Schmutzwasser-Sammelbehälters 3 ist ein Saugrohr 6 geführt.A dirty water receiving space is located in a housing 1 of a vacuum cleaning device 2, in which a dirty water collecting tank 3 is arranged. The dirty water collecting tank can be lifted up through a removable cover 4 provided above. Through the lid 4 and a cover 5 of the dirty water collecting container 3 is a suction pipe 6 out.
Das aufgenommene Sauggut lagert sich im Schmutzwasser-Sammelbehälter 3 ab, während die mitgeführte Luft durch ein Schwimmerventil 9, das bei max. Wasserstand im Schmutzwasser-Sammelbehälter 3 schließt, über eine Absaugleitung 10 zu einem Sauggebläse 11 strömt. Bei geschlossenem Schwimmerventil 9 baut sich in der Absaugleitung 10 ein Unterdruck auf, der vom Druckmeßgerät 17 gemessen wird. Das Druckmeßgerät 17 ist mit einem optischen und /oder akustischen Signalgeber verbunden. Gleichzeitig ist der Ein- und Ausschalter des Saugreinigungsgerätes mit dem Druckmeßgerät derart verbunden, daß bei einem vorgegebenen Druck neben der hör- bzw. sichtbaren Anzeige das Sauggebläse abgeschaltet wird. Dadurch wird ein wirksamer Schutz des Saugreinigungsgerätes erreicht und dem Betreiber zusätzlich noch der Zeitpunkt genannt, an dem der Schmutzwasser-Sammelbehälter 3 zu entleeren ist.The suction material is stored in the dirty water collecting container 3 from, while the entrained air through a float valve 9, which is at maximum water level closes in the dirty water collecting tank 3, via a suction line 10 to a Suction fan 11 flows. When the float valve 9 is closed, it builds up in the suction line 10 a negative pressure, which is measured by the pressure measuring device 17. The pressure gauge 17 is connected to an optical and / or acoustic signal transmitter. Simultaneously is the on and off switch of the vacuum cleaning device with the pressure gauge connected that at a given pressure in addition to the audible or visible display the suction fan is switched off. This provides effective protection for the vacuum cleaning device reached and also given the operator the time at which the dirty water collection container 3 is to be emptied.
